Characteristics that all waves have in common are wavelength, amplitude and frequency. Apart from these properties, different types of waves have a number of varying characteristics. A wave is defined as a repetitive disturbance traveling through a medium going from one location to another.Continue Reading
Wavelength is the distance between one point on a wave to a point on the same part of the next wave. Wavelength is usually measured from crest to crest or trough to trough. The crest is the highest point of the wave, and the trough is the lowest point. Amplitude is the maximum displacement of the wave. The higher the wave, the larger the amplitude is. Frequency is the number of waves in a period of time. The hertz is the unit used for measuring frequency. With sound, a higher frequency indicates a higher pitched sound. With color, different frequencies correlate with different colors. For instance, blue has a higher frequency than red.
Several different types of waves exist. Among the types are light waves, sound waves, microwaves and X-rays. Waves travel at different speeds. Speed is determined by calculating the distance the wave travels divided by the time it takes to travel that distance. The medium affects the speed at which a wave travels. Some waves also carry more energy than others, and some waves are longer than others.Learn more about Tides
Some of the properties which are common to all electromagnetic waves are amplitude, a characteristic frequency and wavelength, and the ability to travel through a vacuum at the same speed, which is commonly referred to as the speed of light. All electromagnetic waves also propagate electrical and magnetic fields in a direction which is perpendicular to their direction of energy flow. The electrical and magnetic fields are in phase and at 90-degree angles to each other.Full Answer >
Tidal waves are caused by the gravitational fields of the sun, the moon and the earth. A tidal wave is a small, regularly occurring wave caused by the shifting of the tide.Full Answer >
Tidal waves are caused by the gravitational pull of the sun and moon on the Earth. The moon's gravitational pull has a greater influence on Earth because it is closer. The moon creates a bulge in the ocean on the side of Earth closest to it.Full Answer >
Three-phase electric power utilizes three conductors that each carry an alternating current, meaning the current first flows in one direction in a circuit and then reverses to flow in the other direction, of the identical voltage amplitude and frequency relative to a common reference. The common reference that power companies usually use is the earth, which serves as one of the wires in the power system. Three-phase motors are popular because they provide consistent voltage.Full Answer >
